When planning a tile installation in your bathroom, kitchen, or outdoors, it’s critical to consider waterproofing. Without the correct waterproofing measures, moisture can penetrate beneath the tile, leading to serious issues like mould growth and structural damage. Thankfully, numerous tile waterproofing methods are available to ensure your project’s longevity and aesthetic appeal.
This guide introduces these methods, highlighting their application process, pros and cons, and suitability for different tile installations.
1. Waterproofing Membranes
A popular choice for many homeowners and contractors, waterproofing membranes are thin layers of waterproof material applied underneath the tiles. This method can be categorized into two main types: liquid and sheet membranes.
Liquid Waterproofing Membranes are a ‘paint-on’ waterproofing system consisting of a liquid applied using a roller or brush. Once it dries, it forms a rubberized and waterproof barrier, preventing water from seeping beneath the tiles.
The main advantages of liquid waterproofing membranes are their ease of application, especially in complex areas like corners and around plumbing fixtures. However, they require a meticulous application process to ensure complete and even coverage, and it might take longer to dry, delaying the tile installation process.
Sheet Waterproofing Membranes: These are sheets of waterproof material that are adhered to the surface to be tiled. They offer reliable and robust protection against water infiltration.
The pros of sheet membranes include the consistency of thickness, which ensures reliable waterproofing across the entire surface.
On the downside, they can be trickier to install, especially around intricate areas, and they may also require more labour and time compared to liquid membranes.
2. Epoxy Grouts
Unlike traditional cement-based grout, epoxy grout is a durable, waterproof, and stain-resistant material that fills the spaces between tiles. It’s composed of epoxy resins and fillers, which gives it superior water-resistant properties.
Epoxy grouts are excellent for areas constantly exposed to water, such as showers, as they require no additional sealing. Their stain resistance also makes them ideal for kitchen backsplashes and counters. However, epoxy grout’s application is more labour-intensive and time-consuming than traditional grout. It’s also more expensive but compensates for the cost with its longevity and minimal maintenance needs.
3. Tile Sealants
Tile sealants are applied to the tile surface and grout lines after installation. These are particularly beneficial for porous natural stone tiles and more susceptible to water damage.
There are two types of tile sealants: penetrating and topical.
Penetrating sealants seep into the tile’s pores, protecting it without altering its appearance. Topical sealants form a protective coating on the tile surface. While they offer excellent water resistance, they may alter the tile’s look and feel.
The application process for tile sealants is relatively straightforward, typically involving a brush or spray. However, they require reapplication over time, depending on the sealant type and the area’s usage.
4. Surface Coatings
Surface coatings, or surface sealers, provide a protective layer on top of the tile and grout, preventing water penetration. They’re commonly used on outdoor tiles or areas with heavy traffic, as they also enhance resistance to wear and tear.
Surface coatings can add a glossy or matte finish to your tiles, enhancing their appearance. However, they can make the tile surface slippery, especially when wet. Like tile sealants, surface coatings must reappear over time to maintain their effectiveness.
Choosing the Right Waterproofing Method
Selecting the right waterproofing solution for your project depends on the type of tile you’re using, the tiled area, and your budget. Here’s a quick summary:
- Waterproofing membranes (liquid or sheet) are great for bathrooms, showers, and other wet areas. They’re also recommended for large surface areas.
- Epoxy grouts work well in places consistently exposed to water and staining, like showers and kitchen backsplashes.
- Tile sealants are suitable for porous tiles, such as natural stone, in indoor and outdoor settings.
- Surface coatings are excellent for outdoor tiles or high-traffic areas, offering waterproofing and enhanced wear resistance.
Remember that these methods can also be combined for optimal waterproofing. For example, a waterproofing membrane can be used with epoxy grout and a tile sealant for comprehensive protection in a shower.
To ensure the best outcome, consider hiring a professional, especially for more complex projects. Not only will a professional installer have the right tools and skills, but they’ll also provide valuable advice on the most appropriate waterproofing strategy for your specific needs.

Primarily, a professional installer comes equipped with the necessary tools and possesses the requisite skill set. They have an in-depth understanding of how to efficiently and effectively apply these waterproofing measures, ensuring a seamless and long-lasting result. Their experience and expertise also mean they’re well-versed in addressing potential challenges or complications that may arise during the project.
Moreover, a professional can offer valuable advice tailored to your specific needs. They’ll assess the situation, understand your requirements and recommend the most suitable waterproofing strategy. This includes selecting the best materials, identifying the most vulnerable areas that need protection, and devising a maintenance plan to prolong the life of your waterproofing system.
Hence, while you can certainly perform some waterproofing measures on your own, for comprehensive protection and peace of mind, enlisting professional help is a worthy consideration.
